Pre-treatment of patchouli lignocellullosic distillation waste with a consortium of microbes viz. Trichoderma harzianum - ATCC PTA-3701, Pseudomonas monteilii - HQ995498, Bacillus megaterium - ATCC 14581 and Azotobacter chroococcum - MTCC 446 significantly enhanced the bio-degradation of cellulose, hemicelluloses and lignin by 58.44 % , 29.44 % and 65.23 % , respectively and improved the yield of vermicompost by 15 % . Application of bioinoculant-enriched vermicompost (BEVC) in patchouli reduced the percent disease index (PDI) of Rhizoctonia root-rot by 36.36 % and improved the essential oil yields by 59.74 % , 37.70 % and 37.96 as compared to plots receiving untreated (not enriched) vermicompost (VC), bioinoculant-enriched compost (BEC) and chemical fertilizers (CF), respectively. Furthermore, BEVC application resulted in a marked improvement in physical (bulk density and water holding capacity) and chemical properties (pH, percent organic carbon, available N, P and K) of the soil. In conclusion, BEVC from distillation waste can be safely utilized as a bio-organic input unambiguously particularly in situations where the use of chemical fertilizers and pesticides is restricted like organic agriculture.
